The recording of my talk at PyData Amsterdam 2024, How I hacked UMAP and won at a plotting contest, is now online. Featuring more than enough Lego figures, dad jokes, and pop culture references. https://lnkd.in/gKZjjGmg In this talk, I share my journey of animating UMAP, a cutting-edge dimensionality reduction algorithm, by visualizing not just its final output but each intermediate step as well. I’ll explain why and how I modified UMAP’s source code, while also demonstrating the use of Polars for data wrangling, Plotnine for visualization, and FFmpeg for animation. The result ultimately earned me a runner-up position in the 2024 Plotnine plotting contest.
